The best hackers and crackers of the Human Sphere are found in Tunguska. The Interventors give crypto logical intelligence support, with combat intelligence data and counterintelligence information. Their main roll is doing electronic war and info-war operations. The Interventors are feared on the battlefield for their capacity to completely stop a whole army. With the communication lines cut off and the remote system collapsed, the soldier is alone. He hasnt got aerial or artillery support or armoured support; he doesnt know where his mates are or whats happening in combat. Hes back in the Middle Ages. This is when all this technology, worm-eaten by an info virus goes against him. And the last thing his eyes will see is the electronic signature of the Interventor projected on to his tactical visor.
